PHOENIX  Hard-throwing Padres starter Andrew Cashner was removed from Tuesday’s game after throwing a warm-up pitch to the backstop in the third inning against the Arizona Diamondbacks. His injury initially was diagnosed as a "strained right lat" muscle.

Cashner, who took a no-hitter in the seventh inning of his first full-fledged start for the Padres last week in Houston, held a 2-0 lead on the Diamondbacks at the time of his departure. He'd struck out the last two batters in the second, including a 101 mph fastball on what turned out to be his final pitch.

After the misfired warm-up, Cashner looked into the Padres dugout and summoned manager Bud Black to the mound.

Traded to the Padres over the winter, Cashner was sidelined by the Chicago Cubs after his only start of 2011, after which he developed a rotator-cuff issue. The Padres had the idea of keeping him in the bullpen for much or all of the 2012 season, but injuries to several other pitchers prompted them to convert him to the rotation.

Cashner's velocity had added yet another aspect to a much-hyped game for the Diamondbacks, who were sending celebrated rookie Trevor Bauer to the mound for his first home start at Chase Field. Cashner was replaced by veteran Ross Ohlendorf, who had been moved from the rotation to long relief.
